Hello boys,
May the Force be with you.
I think the issue isn't so much
oil climbing up out of the pan as the
oil that is being pumped up to the rockers is being held there by lateral forces. Enough
oil is suspended in the valve cover to eventually climb out the breather.
I would run a minimum of a 5/8" hose, preferably 3/4", from each valve cover to a large remote breather (puke tank)
Mount the tank and lines high enough to allow the excess collected oil to drain back from the tank into the valve covers.
Or do like Pat and go to a dry-sump
